A frontal system and weak wave of low pressure will move through the region today, bringing a period of rain during the morning hours. During the afternoon hours and into this evening, additional showers are likely. Overall, I'm forecasting a general .25" to .50" of rain for the Delaware Valley region, with .50" to .75" over some portions of the Lehigh Valley. Some portions of NJ are in moderate drought criteria, so this will help some.
The remainder of this upcoming week, will be mainly dry and temps will be near average. Highs Monday and Tuesday will be near 80, then we can expect cooler highs in the low to mid 70's, for Wednesday through Friday. Overnight lows will be mainly in the 50's for the entire week.
The next chance of some rainfall after today, looks to be on Friday or Friday night, as another cold front moves through the area. This looks to also be a rather light event, with only some showers.
